Autonomous UV Robot with SLAM
By Robin Kanattu Thomas
The affordable autonomous robot provides localization and mapping facilities and safely navigate the robot through the environment.

What inspired you or what is the idea that got you started?
As we face a worldwide healthcare crisis caused by COVID-19, there's a large need for disinfection. Currently, such units are either stationary or moved by humans. We improved upon that concept and built an autonomous, mobile unit that may move around lobbies and hallways to get into rooms for disinfection.
Three Lamps mounted on the robot would emit intense UV light at 240 nm wavelength, as per current medical device standards.
What is your project about and how does it work?
Our key innovation is in making this mobile with a state-of-the-art LIDAR-based SLAM technology that allows operation without exposing the workers to either the harmful UV light or infected rooms of patients. The mobility allows the disinfection of various corners and narrow alleys. We will be using a mobile app to communicate with the robot and the user can see the real-time status of the robot.
The bottom side can be used for other autonomous applications for surveillance, delivery, etc.
What did you learn by doing this project?
Learned ROS, Had to complete the fabrication. This was a complex project. Had to undergo different iterations. We tried testing it with a hospital It was very difficult to make it work. The device failed multiple times. We changed the PCB and we have decided on many changes for the new features.
Future Plan for version 2
Better motors with feedback
Better sensors for human detection.
Proper weight distribution
What impact does your project have on others as well as yourself?
The project once implemented will help in the sanitation of large areas the project will inspire people to build Autonoums SLAM robots for Delivery and Surveillance Purposes.
